Tank maintenance day

[marie]

To show how efficient algae is at taking up nutrients, here is pic of my tank last year just after it sat with no fish in it for 8 weeks. It's also when I first discovered this wonderful red/brown macroalgae.
You can see how pale all the corals are (even the macroalgae was pale at this point) because they were starving. Growth was just about nil on everything except the algae.
